I was running on the treadmill yesterday and stopped mid-run to make an adjustment to my insoles. Directly underneath the ball of my foot (big toe) I have a couple layers of felt about the size of a quarter. During the run, I believed that I was landing too much on the outside of the right foot, feeling I had lifted the ball of t hat foot up too much. It was causing pain on the inside of my ankle. So I stopped and removed the padding. It's just a couple of mm's. Much to my surprise, when I looked at my data after the run I saw this:
Wow - that's quite a change for just a few mm's of padding.
Today - I thought I would try to get the feet matched up, so removed the padding on the other foot, expecting the line to also move towards "0". Instead, I see this:
So when I do the same thing to both feet - why does this metric move towards "0" on one foot and away from "0" on the other foot. Should I interpret this to mean that instead of removing material on the second foot, I should double the thickness? Or perhaps is the data getting interpreted in the wrong direction?
